Igneous
Igneous rock
When molten rock cools and hardens, it forms igneous rock. Igneous rocks can be classified as intrusive (formed beneath the Earth's surface) or extrusive (formed on the Earth's surface). Examples of igneous rocks include granite, basalt, and obsidian.
Igneous rocks form when molten rock (magma) reaches the Earth's surface and cools. It then becomes an igneous rock
The molten material that forms igneous rocks is called magma when it is beneath the Earth's surface and lava once it erupts onto the surface. As magma cools and solidifies, it crystallizes to form igneous rocks. These rocks can be classified into two main types: intrusive (or plutonic), which form from magma that cools slowly underground, and extrusive (or volcanic), which form from lava that cools quickly on the surface.

Igneous rock
Rocks are formed when magma cools and solidifies either beneath the Earth's surface (intrusive igneous rocks) or on the surface (extrusive igneous rocks). As the molten magma cools, it crystallizes and hardens into solid rocks like granite or basalt.
Crystals usually form from molten rock as the molten rock gradually cools.
There are three types of rock - igneous, sedimentary and metamorphic. Igneous rocks formed directly from magma (molten rock flowing under ground) or lava (molten rock flowing above the crust). Granite is an example of what forms as magma cools slowly over a very long time, and obsidian forms when lava cools quickly, such as from contact with ocean water.
Volcanic rocks have two types: intrusive rocks and extrusive rocks. Intrusive rocks, also known as plutonic rocks, form when molten magma cools and solidifies underground. Extrusive rocks, also called volcanic rocks, form when molten lava erupts onto the Earth's surface and cools quickly.
